  Free radicals have been proposed as important causative agents of ageing. The free radical theory of ageing postulates that ageing is caused by free radical reactions. These highly reactive species can cause oxidative damage in the cell. The purposive of this study was to investigate the alteration in plasma lipid peroxidation and erythrocyte superoxide dismutase activity in 2 different ethnic groups of Fars and Turkmen healthy people. We measured plasma lipid peroxidation levels (lipid peroxidation expressed as malondialdehyde) and erythrocyte superoxide dismutase activity. Study include 350 (175 Fars and 175 Turkmen male) apparently healthy individuals. Erythrocyte superoxide dismutase activities were determined in 2 different ethnic groups of Fars and Turkmen consisting of healthy individuals between 26-60 years of age {26-30 (n = 30), 3-35 (n = 30), 36-40 (n = 30), 41-45 (n = 30), 46-50 (n = 25), 51-55 (n = 15) and 56-60 (n = 15)}, respectively. The data was analyzed by Student` t-test. Erythrocyte superoxide dismutase and plasma lipid peroxidation levels in Fars and Turkmen people with 41-45 ages (group 4) and 36-40 ages (group 3) were significantly lower and higher than in the other age groups (Fars groups 1, 2 and 3, Turkmen groups 1, 2), respectively (p< 0.05). There were no significant relation between the age group 4 (Fars people) and the age groups 5, 6 and 7 (p>0.05). There were no significant relation between the age groups 3 (Turkmen people) and the age groups 4, 5, 6 and 7 (p>0.05). We found age-related differences in erythrocyte superoxide dismutase activity and plasma lipid peroxidation levels. The results indicate that the balance between antioxidant and prooxidant factors in free radical metabolism shifts towards increased lipid peroxidation with advancing age in 2 ethnic groups. This situation maybe begin in Turkmen people earlier than Fars people. The ethnic origin, diet, heavy working and life style factors of the two populations may explain this differences. Therefore we propose that older Fars and Turkmen people may have elevated requirement for antioxidants. Supplementation with vitamin or dietary free radical scavengers such as vitamin E and C or foodstuff containing these such as tomatoes, oranges and similars have a potential role in boosting antioxidant related defenses and may be important for older people of two ethnic groups.

  Undernutrition and obesity are two most children health problems in world. Several agents can effect on food pattern among ethnic groups. This study was designed to determine nutritional status among rural children by two ethnic groups (Turkman and Non-Turkman) in north of Iran in 2004. We chose 20 villages of 118 by cluster and simple sampling. All of 2-5 years old children in this area were considered in this study. Sample size was 1446 cases (551 = Turkman and 895 = non-Turkman). Height, weight and personal identification were recorded by questioner. BMI percentile and under -1SD, -2SD and -3SD from NCHS were used for comparison. X2-test and T-test were used to analyze by software SPSS. Turkman children are about 426 g heavier and 4.9 cm taller than non-Turkman in all of age groups. T-test is significant between two groups by weight and height (p< 0.05). Stunting and underweight were observed in Turkman group 13.2 and 1.9%, respectively less than in non-Turkman by -2SD criterion. There is a significant difference between two groups by stunting (p< 0.05). Obesity and overweight exist in Turkman group 24.5 and 2.6%, respectively are less than in non-Turkman. Obesity is statistical significant between two groups (p< 0.05). Secular growth in two groups is incompatible and in Turkman group, it is better than Non-Turkman. There is severe height deficit in Non-Turkman group and it increases the BMI values. Thereby, malnutrition is the most health problem in rural area in north of Iran and nutritional intervention is necessary for solving these problems. BMI values are not suitable for children with stature failure.
